Definitions
- Security elements encased in a131veriack layer for securing goods and cast or injection-molded parts which contain such parts for theft protection.
- the invention relates to security elements encased in a powder coating layer for securing goods and to cast or injection-molded parts which contain such parts for theft protection.
- the individual securing elements contain a magnetic material with high permeability and low coercive force (soft magnetic material) and a magnetic material with low permeability and high coercive force (semi-hard or hard magnetic material).
- soft magnetic material soft magnetic material
- spin-hard or hard magnetic material a magnetic material with low permeability and high coercive force
- the soft magnetic components of the securing elements described above have at least one magnetic preferred axis.
- Securing elements of the type described above are preferably used in the area of electronic article surveillance in department stores and warehouses.
- a particularly advantageous embodiment of a securing element has become known from EP 0 295 028 B1.
- the so-called thin-film fuse elements are described. These consist of a thin layer of soft magnetic material, preferably in the ⁇ m range. The layer is e.g. applied to a carrier substrate by means of a physical deposition process under vacuum conditions.
- Thin-film fuse elements show an anisotropic structure.
- Anisotropic means that the soft magnetic layer from which the thin-film fuse elements are formed has a preferred axis.
- the anisotropic structure is noticeable in practice by the fact that the thin-film fuse element as The response to a characteristic signal remitted to a query field is maximum if the query field and preferred axis are aligned parallel to one another; the signal disappears, however, if the preferred axis and the query field are perpendicular to each other.
- strip elements which consist of a strip-shaped, soft magnetic material, also show an analogous behavior.
- the characteristic signal is at a maximum when the query field and stripes are aligned parallel to one another, and disappears when the alignment is vertical.
- the strip element can also consist of a drawn wire. Such a strip element is proposed for example in DE 197 53 500 A1.
- Securing elements of the type mentioned are currently mostly attached to the goods to be secured as part of price or barcode labels.
- this way of attaching the securing elements to the goods has some disadvantages:
- the distance between the soft and hard magnetic components in the still soft injection molding or casting compound increases. If you now apply the magnetic field required to deactivate the securing elements, the hard magnetic components are magnetized as intended. However, the permanent magnetic field caused by the hard magnetic components is too large due to the resulting spatial distance between the potted soft and hard magnetic components of the securing element in order to further prevent reliable suppression of the transmission of the characteristic signal.
- the smaller components of the security element that are loosely present in the injection molding compound can adversely affect the production process, for example due to a blockage of the spray nozzles.
- the sheathing of the securing elements is primarily carried out in order to protect the metal parts of the securing element from oxidation and the protected goods from contamination by metal and metal oxide.
- the same problems also arise in the production of these coated securing elements as in the production of cast or injection molded parts.
- the extrusion nozzles are often blocked by detached components of the securing elements.
- the object of the present invention is therefore to propose securing elements of the type described in the introduction, which are protected against detachment of the soft magnetic from the hard magnetic components.
- the task is solved by securing elements, at least partially by one
- Powder coating layer are covered.
- Securing elements are present as a film or are designed as strips.
- Contain metal powder for example steel powder.
- Spray compound can be introduced, so that the securing element for one
- Fig. 1a A longitudinal section along the line A-A through a deactivatable, film-shaped securing element, the soft magnetic components are designed as a film.
- Fig. 1 b A side view of the same security element
- Fig. 2b A top view of the same securing element
- Fig. 3 A longitudinal section along the line B-B through a securing element as shown in Figures 2a and 2b, the securing element now having a casing.
- FIG. 1a shows a longitudinal section along the line A-A through a deactivatable, film-shaped securing element 1, which has a thin, soft magnetic film 3.
- a hard magnetic material such as nickel, is also applied to this film.
- This hard magnetic film 2 has openings or holes 4 in the vertical direction, and is therefore perforated.
- Figure 1 b shows the same securing element 1 in a side view.
- Figure 1 c shows the film-shaped securing element shown in the two previous figures in a top view of the perforated hard magnetic film.
- the holes or passages were shown too large in relation to the securing element for reasons of clarity.
- the openings have a diameter of 1 to 2 millimeters while the securing element can have an area of several square centimeters.
- FIG. 2a shows a side view of a strip-shaped securing element 5 that can be deactivated.
- This securing element is composed of a soft-magnetic strip 6 and hard-magnetic sections 7.
- Figure 2b shows the same securing element in plan view.
- Figure 3 shows a longitudinal section along the line BB through a strip-shaped securing element 5 as shown in Figures 2a and 2b.
- the securing element shown in FIG. 3 has a coating made of powder coating 8.
